Use of Intermediate Endpoints in the Economic Evaluation of New Treatments for Advanced Cancer and Methods Adopted When Suitable Overall Survival Data are Not Available

Development of a framework and decision tool for the evaluation of health technologies based on surrogate endpoint evidence

In the drive toward faster patient access to treatments, health technology assessment (HTA) agencies and payers are increasingly faced with reliance on evidence based on surrogate endpoints, increasing decision uncertainty. Despite the development of a small number of evaluation frameworks, there remains no consensus on the detailed methodology for handling surrogate endpoints in HTA practice. This research overviews the methods and findings of four empirical studies undertaken as part of COMED (Pushing the Boundaries of Cost and Outcome Analysis of Medical Technologies) program work package 2 with the aim of analyzing international HTA practice of the handling and considerations around the use of surrogate endpoint evidence. We have synthesized the findings of these empirical studies, in context of wider contemporary body of methodological and policy-related literature on surrogate endpoints, to develop a web-based decision tool to support HTA agencies and payers when faced with surrogate endpoint evidence. Our decision tool is intended for use by HTA agencies and their decision-making committees together with the wider community of HTA stakeholders (including clinicians, patient groups, and healthcare manufacturers). Having developed this tool, we will monitor its use and we welcome feedback on its utility.

Research on the Economics of Cancer-Related Health Care: An Overview of the Review Literature

We reviewed current literature reviews regarding economics of cancer-related health care to identify focus areas and gaps. We searched PubMed for systematic and other reviews with the Medical Subject Headings "neoplasms" and "economics" published between January 1, 2010, and April 1, 2020, identifying 164 reviews. Review characteristics were abstracted and described. The majority (70.7%) of reviews focused on cost-effectiveness or cost-utility analyses. Few reviews addressed other types of cancer health economic studies. More than two-thirds of the reviews examined cancer treatments, followed by screening (15.9%) and survivorship or end-of-life (13.4%). The plurality of reviews (28.7%) cut across cancer site, followed by breast (20.7%), colorectal (11.6%), and gynecologic (8.5%) cancers. Specific topics addressed cancer screening modalities, novel therapies, pain management, or exercise interventions during survivorship. The results indicate that reviews do not regularly cover other phases of care or topics including financial hardship, policy, and measurement and methods.

What Does Society Value About Cancer Medicines? A Discrete Choice Experiment in the Belgian Population

BACKGROUND

Debate on pricing and reimbursement of cancer medicines highlights the need to establish the value of cancer medicines.

OBJECTIVE

This study aims to elicit the trade-offs in cancer medicine characteristics that the Belgian population is willing to make.

METHODS

A discrete choice experiment used six attributes with three levels each, based on literature and focus group discussions. The survey was sent to a random sample of 3500 Belgian citizens. Based on the choice of 961 respondents, individual parameters were estimated with a mixed logit model.

RESULTS

Societal value of cancer medicines was positively affected by a higher number of patients eligible for treatment, a high initial life expectancy and quality of life of patients, a high gain in quality of life and life expectancy due to treatment, and a low treatment cost. The value of 1-year gain in life expectancy was independent from the initial life expectancy of the patient. However, the value of one-point gain in quality of life was higher for patients with a low initial quality of life than for patients with a high initial quality of life.

CONCLUSIONS

This study has shown that gain in quality of life with cancer medicines is valued higher by Belgian society for patients who have lower initial quality of life before the start of treatment.
